Emergency Response Team

The Trempealeau County Sheriff's Office Emergency Response Team (ERT) is a combined unit consisting of highly trained personnel from the Sheriff's Office and three municipalities within the county. ERT members are full-time law enforcement deputies / officers who, in addition to their regular assigned patrol duties, commit to the extra training and responsibilities required to be a member of the team. The Emergency Response Team are subject to "call-out" 24 hours a day.

Each member is trained to perform high-risk operations that fall outside of the abilities of regular officers. ERT is equipped with specialized firearms and equipment that allows them to effectively deal with hazardous or threatening situations to include hostage rescues, counter-terrorism operations, high risk arrests or search warrants, subdue barricaded suspects, and engage heavily-armed criminals.

ERT duties include:

  • Hostage rescue

  • Crime suppression

  • Riot Control

  • Perimeter security against snipers for visiting dignitaries

  • Rescue officers and citizens captured or endangered by gunfire

  • Counter terrorist operations/Homeland Security

  • Resolve high-risk situations with a minimum loss of life, injury, or property damage

  • Resolve situations involving barricaded subjects

  • Stabilize situations involving high-risk suicidal subjects

  • Provide assistance on drug raids, arrest warrants, and search warrants

  • Provide additional security at special events

  • Stabilize dangerous situations with violent criminals (such as rapists, serial killers or gangs)

  • Armed patrols

The Emergency Response Team has and continues to be utilized by municipalities within Trempealeau County and has provided mutual aid response to jurisdictions outside of Trempealeau County.
